[SOLVED]Compare bitmaps?

Hello!

Is there an easy way to check if two bitmaps are the same, not reference wise but contains the same pixel data? I gues I could extract all the pixels and compare the arrays, just wondering if there is an easier way?

Regards/Per

Hi,

you can calculate a hash value out of the image data and compare the hash value instead of the whole image.

Thanks for the suggestion. I did solve it in another way (compare the resource id)

So what I did earlier with comparing pixels was a bit overkill.
